Description Thomas Haller 2017-02-17 12:42:40 UTC
+++ This bug was initially created as a clone of Bug #1367551 +++

For bug 1367551, we changed behavior for rc-manager=symlink setting upstream: 
https://cgit.freedesktop.org/NetworkManager/NetworkManager/commit/?id=15177a34be297654086005f2d796e6a4c6a1b918

This change will also go to rhel-7.4.


This bug is only as a marker to fill a proper changelog, and possibly add some testing for it.

The change is suitable for rhel-7.4 because:

- the default on rhel7 is rc-manager=file. So, this likely does not affect many users.

- the new behavior makes much more sense, the difference comes into play when

  - if somebody has rc-manager=symlink
  - /etc/resolv.conf is a regular file or missing

Previously, NM would have replaced /etc/resolv.conf with a symlink to /var/run/NetworkManager/resolv.conf. Now, instead NM will write resolv.conf as a regular file. A user who intentionally chooses rc-manager=symlink likely already replaced /etc/resolv.conf with a symlink (which is the main use of this mode).
